To all whom it mag concern p Y Be it known that'I, JARED Pn-Ais'rnn, ofMelros'e-,'- in the county of Middlesex and State of lVI-assachusetts',have invented c'ertain new anduseful'lniprovements in Non- 1 RefillableBottles, of which the following i is a specification. V,

This invention has for its object to proi vide-asiniple, durable,eliicientand rela tively inexpensive anti-refilling attac hinent adaptedto be applied to a bottleneck of ordinary shape and to be constructecflof a material or materials su'ch as glass; the use of which is -notobjectibnablein devices for this purpose;

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings "which form a part of this specification,Figure 1 represents an end'view of anattachment embodying 'my invention;Fig." 2 represents a side elevation of the same, F ig's. 1 and 2 showingthe preferred size of the. attachmen't; Fig. 3 represents an enlargedsection Online 33 of Fig. 2 showing'jthe attachment in place in abottleneck; Fig. 4 represents a section on line ofFig. 3; Fig. 5represents a view similar to Fig. 3"showingthe bottle neck inverted forpouring; and Figs. '6 and 7 represents views similar to Fig. 3 showingthe bottle neck held horizon tally as it would be in attemptingto refillthe bottle.

Similar reference characters indicate the same or similar parts in allthe figures.

In the drawings, 12 represents a plug formed to be inserted in a bottleneck 13,

the periphery of the plug being preferably.

tapered or frusto-conica l; andtheinterior of the bottle neck beingcorrespondingly formed to have a close fit on the periphery of the plug.The plug may be immovably secured in the bottleneck by any suitablemeans such as a cement composed of soluble glass, although if desiredothermeans may be employed for securing the plugin place and preventingits removal.

In the inner end portion of the plug is formed a valve chamber 14,having a. flat annular bottom 15, which surrounds a passage 16communicating with the interior of the bottle. The circular wall 14 ofthe valve chamber intersects the valve seat- 15 and its outer portion iscurved or inclined 1 at 1 1", said portion overhanging the valve seat 15and mergingin'to the concave or dome shaped top 14 of the chamber. p

The portion '14P ofthe circular walljof the valve chamber is inclinedoutwardly to the curvejcl portion 14 said portion 14 having therefore agradually increasing diameter from the valve seat outwardly to cause thevalve hereinafter. described to drop slight-1y when it is displacedoutwardly, and thus assume an eccentric position when the bottle is heldin an apjoroximately horizontal position'. In other \v'ords. when thevalve is'clis.

placed outwardly it drops edgewise so that only its lower edge portionbears on the wall of the valve-chamber, its upper edge portionbeing'separated from said wall. p

In the periphery of thepl'ug are formed a series of longitudinal ducts17 which extend through the outer end of the plug. The outer portions17* of the bottoms of said ducts are'preferably; parallel with theeriphery of the lugso that the outer portions of the ducts are ofsubstantially uniform depth from their outer ends art way to their innerends. The inner portions,-17" of the bottoms of the. ducts are inclinedinwardly and intersect the outer part of the curved portion 14:" of thevalve chamber wall the object of the inclination of the portions 1'7being to guide liquid inwardly against the periphery and outer side ofthe va1ve ,as' hereinafter described. The sides of the ducts 17 areextended inwardly beyond the inclined bottom portions 17 and terminatein abutments 17 which are located-abov the valve seat. The extendedportions of the sides of the ducts, the abutments l7, andthe inner endsof the inclined bottom portions 17 form marginsof' inclined ports 17 whih are caused'by the curved portion 149 of the valve chamber wall tooverhang the valve seat.

tively thin disk having substantially flat sides, the inner side of thevalve being adapted to close on the seat 15 and form a liquid tightjoint therewith. The diamee 18 represents the valve, which is a relaterof the valve is substantially equal to. that of the valve seat, so thatwhen the valve is seated, it substantially fills the lower portion .ofthe outwardly inclined wall 14*, and its thickness is such that when thevalve isdisplaced from the seat, its outer side abuts against the curvedportion 14 of the valve chamber wall, and is arrested thereby with itsouter side separated from the top 14: and

against the seat.

from the outer ends of the ports 17 the inner side of the valve being atthe same time separated from the inner ends of said ports formed bv theabutments It will now be seen that when the bottle is inverted, as shownby Fig. 5, liquid is permitted to flow outwardly from the inner portionsof the ports 17 across the periphery of the valve and through the ducts17. It will also be seen that when the bottle is held in anapproximately horizontal position and fluid under pressure, eitherliquid or air, is forced inwardly through the ducts, such fluid willimpinge on the periphery and the outer side of the valve and will bedeflected inwardly toward the center of the outer side, thus exertingpressure which promptly closes the valve.

When the bottle is held horizontally the valve naturally assumes aninclined position, as shown by Figs. 6 and 7 Whether the inclination bein one direction, as shown by Fig. 6, or in the opposite direction, asshown by Fig. 7 fluid pressure through all the ducts will be exerted onthe outer side of the valve and will force it to its seat as indicatedby dotted lines in Fig. 6.

The abutments 17 at the inner ends of the ducts are adapted to arrest atampering instrument such as a wire employed in an etfort to beat thedevice, such instrument being guided by the outer portion of the duct,(made of uniform depth as above stated) against the abutment. In casethe tampering instrument enters the valve chamber through the upper duct(the bottle being held horizontally) it will pass between the upper edgeof the then eccentrically located valve and the wall of the valvechamber and abut ineffectively against the valve seat. A tamperinginstrument inserted through the lower duct will of course abut againstthe outer side of the valve and simply force it The ducts are preferablyof zig-zag form, as shown by Fig. 2, to increase the difiiculty ofinserting a tampering instrument.

The combined cross sectional area of the ducts is such that they willcollectively carry off, without clogging, the quantity of liquid whichpasses through the passage 16 surrounded by the valve seat, and willalso permit the entrance into the bottle of sufficient air to replacethe escaping liquid. The periphery of the valve is preferably rounded orcurved, as shown, to reduce the bearing of the valve on the wall of thechamber and minimize frictional resistance to its sliding movement onsaid wall. The abutments 17 c at the inner ends of the ducts not onlyserve as above stated to resist inward movement of a tamperinginstrument, but also to assist in deflecting inwardly any fluid that maybe forced from the outside into the ducts. The zig-zag form of the ductsis not considered indispensable, since the other provisions hereindescribed for frustrating attempts to beat the device would beefficacious if the ducts were straight.

Important structural features distinguishing my invention are thefollowing, first, the disk valve having a continuous circular edge, thediameter of which is substantially equal to the greatest diameter of thevalve seat; second, the outward and upward in clination of the circularwall of the chamber from the valve seat outwardly; third, the inwardinclination or curvature of the circular wall from the outwardlyinclined portion of said wall to the top of said chamber; fourth, theconcave or dome shape of said top; and fifth, the ducts 17 formed in theperiphery of the plug 12 and extending through the outer end of the plugpartly to the inner end; abutments 17 being formed at the inner ends ofthe ducts. These features all contribute to the successful operation ofthe device. The described diameter of the valve and the continuity ofits circular edge insures the interposition of said edge between thewall of the passage 16 and the ports 17 both when the valve is closedand when it is opened. Then the valve is closed its margin is betweenthe passage 16 and the inner ends of the ports 17, and when the valve isopen its margin is between said passage and the outer ends of the ports,so that liquid may flow freely through each of the ports. Theinclination of the circular wall of the valve chamber enables the valveto move entirely from its seat when the bottle is in pourin position, sothat none of the ports are obstructed by the valves when the latter isopen. The curved form of the top of the valve chamber, and the intersection of the inner ends of the ducts with the marginal portion ofsaid concave tfop insures the formation of a space between the top ofthe chamber and the outer side of the valve when the latter is open,said space communicating with the outer ends of all the ports so thatwhen liquid is forced inwardly through the ducts, it is caused toimpinge against numerous points on the outer side of the valve and closethe latter.
